Quick answer
To receive a purchase order with serial numbers in Business Central from a phone, create
the Warehouse Receipt from the purchase order, assign it to the warehouse user, then in
Plur-e Mobile open the receipt, scan each serial number once, send the serials and post.
Business Central creates the Posted Warehouse Receipt with item tracking lines — no
typing on a terminal.
Receiving is where inventory accuracy is won or lost. When serial numbers are typed into Business Central after the fact, they arrive late, with transposed digits, or not at all. This post shows the flow Plur-e customers use to capture serials at the dock, and what Business Central does with them.
Transfer orders and some purchase orders already carry serials. In that case there is nothing to scan: the app shows the preloaded list, the operator verifies the physical units and confirms. This is common for inter-warehouse transfers where the shipping site already registered the serials.
